Psychometrics, a specialized branch within psychology, is dedicated to the theory and methodology of psychological measurement. This discipline encompasses the development and refinement of testing instruments, measurement techniques, and assessment procedures aimed at quantifying latent psychological constructs—attributes not directly observable but inferable through systematic analysis. Such constructs include intelligence, personality …
Item Response Theory (IRT) is a widely adopted framework in psychological and educational assessments, used to model the relationship between latent traits and observed responses. This recent work introduces an innovative approach that incorporates group-theoretic symmetry constraints, offering a refined methodology for estimating IRT parameters with greater precision and efficiency. …
Anselmi, Robusto, and Cristante (2023) propose a novel approach to improving Computerized Adaptive Testing (CAT) by integrating unidimensional test batteries. This method aims to enhance both the accuracy and efficiency of ability estimation by dynamically updating prior estimates with each test response. Background Computerized Adaptive Testing has been a widely …
The Jouve-Cerebrals Figurative Sequences (JCFS) is a self-administered test designed to measure nonverbal cognitive abilities, focusing on pattern recognition and problem-solving. This post outlines the psychometric evaluation of the JCFS, emphasizing its reliability and practical applications while acknowledging areas for future development. Background The JCFS was developed to provide a …
The Jouve-Cerebrals Word Similarities (JCWS) test offers a detailed approach to assessing vocabulary and verbal reasoning abilities. This post examines the psychometric properties of the test, focusing on its reliability, validity, and potential applications in academic and clinical settings. Background The JCWS test builds on the foundation established by the …
The I Am a Word (IAW) test represents a distinct method for assessing verbal abilities, offering an open-ended and untimed format designed to accommodate a diverse range of examinees. This approach promotes genuine responses while fostering inclusivity and engagement in testing environments. Background The IAW test emerged as a response …
Abstract This research focused on assessing the reliability of the Jouve Cerebrals Test of Induction (JCTI), a computerized 52-item test measuring nonverbal reasoning without time constraints. The reliability of the test was determined through Cronbach’s Alpha coefficients and standard errors of measurement (SEm), calculated across various age groups. A total …
Abstract This study aimed to revise the Epreuve de Performance Cognitive (EPC), a nonverbal, sequential reasoning test, by incorporating a stopping requirement after five consecutive misses, and to evaluate the psychometric properties of the revised EPC. Data from 1,764 test takers were analyzed using various statistical methods. The revised EPC …
Abstract The TRI52 is a computerized nonverbal intelligence test composed of 52 figurative items designed to measure cognitive abilities without relying on acquired knowledge. This study aims to investigate the reliability, validity, and applicability of TRI52 in diverse populations. The TRI52 demonstrates high reliability, as indicated by a Cronbach’s Alpha …
Abstract The Cerebrals Cognitive Abilities Test (CCAT) is a psychometric test battery comprising three subtests: Verbal Analogies (VA), Mathematical Problems (MP), and General Knowledge (GK). The CCAT is designed to assess general crystallized intelligence and scholastic ability in adolescents and adults. This study aimed to investigate the reliability, criterion-related validity, …
